Hilary Duff has had her weight scrutinized over the last few years -- for a while there, she was scarily thin -- but she seems to have a healthy amount of muscle and some feminine curves now, and she gives some of the credit to Pilates.

The erstwhile Lizzie McGuire actress told People magazine, "I was a gymnast before, so I was a bit more bulky in the past. [Now] I have leaner, longer muscles, my strength is up."

Looks to me like she's found a great balance of healthy eating and exercise -- perhaps due in part to her relationship with a professional hockey player. At any rate, it's great to see her looking strong and healthy!

How does Dancing With the Stars judge Carrie Ann Inaba stay so fit? Well, obviously dance plays some role, but she credits her upbringing with her healthy diet.

Friday Night Lights star Minka Kelly loves her curves, and she's not alone. Charlize Theron has also made it known that she thinks her curves belong right where they are, and that they make her feel "pretty hot."

Joining the "I love my curves" club is recent mama Christina Aguilera, who has worked hard to get her tummy flat and toned, but admits she's "okay with the booty and the boobs."
